  Investigating

  Jan 12 · 12:17 PM CodeTwo

  We are currently experiencing a localized backend communication issue between Azure services in the UK region, which affects the ability of some customers to sign in using Microsoft accounts to the Signature Management page (app.codetwo.com) and manage their rules and signatures. All indicators suggest that this is an issue on Microsoft’s side: we have not made any changes today, and the exact same configuration works without interruption across our other nine regions and eighteen datacenters. We are actively investigating the issue. All other services remain fully operational, and email signatures continue to be added as usual. No action is required on your side at this time. Please stay tuned for further updates here.

  Monitoring

  We switched the affected nodes to alternative, healthy resources within the region, which appears to have resolved the issue. We are no longer seeing any sign-in timeouts or errors. We will continue to monitor the situation.
